¶ 1. Guy R. Willett appeals from an amended judgment that changed the sentencing structure four months after the original sentencing. The sentencing court originally held that the sentences for the three convictions which were before the court that day could not be served consecutively to a sentence Willett was to receive four days later when his probation was revoked. A third of a year later, the court was convinced that its original ruling was based on an erroneous understanding of the law and changed the three sentences so that they were consecutive to the later sentence. We agree with Willett that this modification violated the prohibition against double jeopardy because it defeated Willett's legitimate expectation of finality in the sentence. We reverse and remand with *623 directions that the trial court amend the judgment of conviction to conform to the original judgment.
¶ 2. Willett was originally charged with two counts of arson. Pursuant to a plea agreement, Willett pled no contest to one count each of arson, negligent handling of burning materials and recklessly endangering safety, pursuant to Wis. Stat. §§ 943.02(1), 941.10(1), 941.30(1) (1997-98).

The trial court imposed and stayed four years of prison and forty years of probation on the arson count and a total of fourteen years of prison on the other two counts. The prison sentences were to be served consecutively to each other, but not consecutive to another prison term that Willett was to receive four days later when his probation was revoked in another case.

The trial court stated that it wanted to make the sentences consecutive to the sentence in the other case, but that it did not believe it had the authority to do so because Willett was not yet serving that sentence. The State asked the trial court, "[Wjould the court be inclined to order this be consecutive if the court thought it had the authority to do so or not?" The court responded, "If there is authority, it would be my intent it be consecutive to any probation revocation sentence. I don't believe there's the ability statutorily for that to occur." The State suggested that the court stay the sentencing order to a later date so that it would not become effective until after the other sentence had been imposed. The court declined to do so, but noted on the judgment of conviction that the "Court intends to make sentence

consecutive to probation revocation — if this can occur pursuant to statute then to be served consecutive." On May 10, 1999, the State sent the court a letter calling the court's attention to

¶ 5. This court recently addressed a case similar in posture to the present case.
See Burt,
[W]e conclude that a defendant's interest in the finality of his or her sentence is not a significant concern when the trial court simply corrects an error in speech in its pronouncement of the sentence *626 later in the same day. Unlike in North, where the trial court did not attempt to correct its sentencing error until over three months later, Burt did not have a legitimate expectation that [the trial court] could not correct his slip of the tongue on the day of sentencing.
Burt,
¶ 6. Here, the facts dictate the opposite result because Willett did have a legitimate expectation of finality. First, the State's argument that Willett knew the sentence might change is unpersuasive. Yes, Wil-lett heard the prosecutor say that he would look for authority allowing the court to impose a consecutive sentence. But Willett also heard the trial court reject the prosecutor's suggestion that the order be stayed. Further, he heard the trial court proceed to impose his sentence. Second, unlike Burt, who was resentenced on the same day, Willett had already been serving his sentence for four months when the trial court changed it from concurrent to consecutive. Third, and perhaps most important, this was not a "slip of the tongue" on the part of the trial court. Here, the trial court had an incorrect understanding of the law governing its sentencing authority. Double jeopardy prevents the State from using this error, four months later, to seek a stiffer sentence for Willett. That the trial court wanted to impose a consecutive sentence to begin with is of no moment; what the trial court actually did was impose a valid, concurrent sentence. Our reading of the transcript of the original sentencing hearing convinces this court that those proceedings fostered in Willett a legitimate expectation of finality in the sentence. The double jeopardy clause prevents the trial court from going back, four months later, to redo the sentence.
*627 ¶ 7. We remand for the trial court to enter a farther amended judgment that clearly states that the sentence commenced on noon of the day of the original pronouncement. See WlS. Stat. § 973.15(1).
By the Court. — Judgment reversed and cause remanded.
